Description

This module implements reading of tagged PDF content from PDF files.

Methods

This class inherits from PDF::Tags and has its methods available.

method read

method read(PDF::Class :$pdf!, Bool :$create) returns PDF::Tags

Read tagged PDF structure from an existing file that has been previously tagged.

The :create option creates a new struct-tree root, if one does not already exist.

method canvas-tags

method canvas-tags(PDF::Content::Canvas) returns Hash

Renders a canvas object (Page or XObject form) and caches marked content as a hash of PDF::Content::Tag objects, indexed by MCID (Marked Content ID).
